In 1965 Bell flew the Bell Model 209 – the prototype of the world’s first dedicated attack helicopter. This machine was specially designed as an escort for troop carrying helicopters to meet a US Army requirement. The whole development was completed in very short terms. Eventually this machine was a turning point in the development of helicopter technology and its application. This armored gunship was a step forward from the previous transport helicopters, that carried only defensive weapons. It opened a new era in warfare.
